In 1970 the countries in the Northern, Central and Southern America were affected the most and few countries in the middle east witnessed terrorist activities. During this year United States of America was the worst affected nation. Around 1976 1977 and 1978, terrorists activities were seen in countries belonging to European, Asian and Sub Sahara African regions and also in the Soviet Union and this can be considered as the time when terrorism started spreading in the world. Through 1984, most number of terrorist events occurred in Peru and Chile and continued to do so until 1988 where India also was affected along with them. In 1992, it can be observed that almost every country in the world had faced terrorism. The year 1998 saw decrease in the terrorist events but that didn’t last for long as from the year 2005 there was constant increase in the number of attacks all over the world and 2014 was the year which has recorded most number of terrorist attacks. In 2014, countries like Iraq and Pakistan suffered the most with 3933 and 2151 attacks respectively.
The stacked barplot represents twenty countries that are most affected by terrorism. Iraq continues to be the country most impacted by terrorism. ISIL is responsible for all the terrorists attacks in Iraq Most of the attacks include bombing and explosion. After the withdrawal of US troops from Iraq, civil war broke, which led to the formation of ISIL and increased attacks on Iraq.
The above linegraph represents the number of attacks all over the world from 1970 to 2017. As can be observed from the graph that on an average terrorism around the world has always increased until 2014. There were few years like from 1997 to 1998 where there was a sharp decrease in terrorists activities. The world in 2014 witnessed most terrorist attacks, this is due to the allegiance of two terrorist groups Boko Haram and ISIL, They were were jointly responsible for 51% of all claimed global fatalities in 2014. 78% of all deaths and 57% of all attacks occurred in just five countries: Afghanistan, Iraq, Nigeria, Pakistan and Syria.
The treemap gives us the information about distribution of the various attack types across the Indian cities. Compared to other cities, the city of Srinagar was attacked by almost all the methods and it can be inferred from the chart that it was bombed many number of times. Imphal is the second most attacked city.
The network chart tells us whether the terrorists groups organise their attack based on the regions in India. Some groups attack only one region like LeT in North and ULFA in the eastern part of the country. There are also groups which attack more than one region like the PWG attacks both central and southern regions. Maoists and CPI- Maoists are the only two groups which attacks all the regions except the north.
The spider chart represents the most used attack methods by the terrorist groups in India over the years. It can be observed that bombing accounts for almost 50% of the attacks. The second method that was preferred was armed assault which constitutes 25%. Hostage taking and Unarmed assault were the least preferred methods among the terrorists groups.

Naxalite–Maoist group name looks the most prominent as the most dangerous terrorist group in India with more than 1400 attacks followed by another Naxalite group operating in Andhra Pradesh region by People’s War Group (PWG). These groups target Government in general by staging attacks against military, police and government. Other equally responsible groups for terrorism are Muslim Militants, Bodo Militants and Sikh Extremists.
## Links is a tbl_df. Converting to a plain data frame.
Terror Attacks on United States are in decline since the highest spike in 1970s. Bombing/Explosion has been the most used attack type over the years with a high of 278 explosions in 1970 and the lowest being 2 incidents in 2008,2009 and 2012. The above Sankey plot helps us to understand the exact flow of attack incidents by year and attack type by interactively showing us the number of attacks per year for a given type while also showing us the distribution of attack types by cities, where we can see that California, New York and Puerto Rico are the 3 cities who have received a cumulative attacks of more than 100 over all the years from 1970 to 2017.
The majority of attacks in United States have taken place in the year 1970, which, we can see targeted everything with few target categories like Military, Police, Telecommunication, Other and NGO’s being targeted the most. The years after 2000 witness a medium to high frequency of attacks with attacks targeting Religious Figures/Institution, Police and Transport. The overall level of terrorist-related acts in the United States declined in the early 1990s, when compared to figures for the 1970s and 1980s, but has increased steadily during the early 2000’s years.
FALN separatist organization in Puerto Rico which used violence in its campaign for Puerto Rican independence from the United States contributes to the highest attacks in 70s and then after rapidly declines reducing to 0 attacks after the 90s. Also, between 1973, when the Supreme Court decided abortion should be legal throughout the United States, the US has been the target of anti abortion extremists attacks facing more than 300 acts of extreme violence. The third group attacking the United States for more than four decades is the Animal Liberation Front (ALF).
We can observe that the use of explosives have been in a decline since the 70s but in contrast the use of incendiary saw an increase from the 70s to 2000s and then decline there after. But, we should be more concerned as the use of biological and chemical weapons have been in rise from early 80s and 70s respectively which would prove more lethal than explosives or incendiary weapons.

USA doesn’t witness many terror attacks as compared to India.There are very few attacks that have claimed a very large number of lives. Also the number of causalities on an average is less as compared to that of India. It has however witnessed one of the worst terrorist attacks in 2001 in New-York, which killed more than 1500 people.
Gun violence in the US results in tens of thousands of deaths and injuries annually. In 2013, there were 73,505 nonfatal firearm injuries which included 11,208 homicides, 21,175 suicides, 505 deaths due to accidental or negligent discharge of a firearm, and 281 deaths due to firearms use with “undetermined intent”. From the above graph, we can observe that the number of gun violence incidents are increasing every year. In the year 2014, there were about 51 thousand incidents reported. The number increased to 53 thousand in the next year, 2016 saw a bigger jump with close to 58 thousand incidents reported, in 2017. The number of gun violence incidents further increased to 61 thousand. A big increase of 10,000 incidents have been observed from 2014 to 2017, and this number is expected to further grow. In the purview of the statistics shown by the grouped bar charts it is vividly clear that gun violence is the biggest issue in United States in comparison to terrorism.
## Adding missing grouping variables: `date`
The following rose chart displays the comparison of violence type and its affects distributed among different cities of United States where California tops with approx 16000 incidents reported. Florida with 15,000 incidents and Texas with 13,000 and it narrates the same story that gun violence is the greater evil than overall terrorism in United States.
In the above scatter plot, we tried to get a generally idea on how GDP of a country gets affected by terrorist attacks. For this purpose, we chose few developed and developing countries for our analysis. As it is clearly visible from the graph that there exists a negative correlation between total attacks and GDP of a country. As number of attacks increase, the GDP decreases. There could be several other factors for the fall in GDP, number of terrorist attacks is one of them.
In the above correlation plot, we tried to find the correlation between terrorism and various factors that contribute in calculating the happiness score of a country. We did not get any robust results in this plot except for the negative correlations between terrorism and family & terrorism and freedom. We thought that the data could be acting in a biased manner as whole, so, we decided to dive deep into the data and work on small and distinct sets of data which will help us to understand a general picture.
Similar to the above plot, we can see that there is a negative correlation between terrorism and family, terrorism and freedom. Hence we conclude that as freedom increases, number of terrorist attacks decrease and as terrorists events grow, family (have someone to count on in times of trouble) diminishes.
For developed countries, we get more number of correlations with terrorist attacks as compared to developing countries it can be observed that there is a strong negative correlation between freedom and terrorism & terrorism and government’s free from corruptions, which makes sense as more the government is trusted and free of corruptions, less terrorist attacks takes place. Additionally, we can see that health life expectancy also dwindles when terrorist attacks escalate. The next correlation states that people tend to donate more where the number of terrorist attacks are more.
In the case of African region, we found an interesting but implausible relation which states that people are more happy where number of terrorist activities are more and also family and terrorism are inversely related, which should not be the case.
In the case of Arab region, we can see the same relationships as established in the African correlation plot only its more stronger as compared to the previous correlation.
In the countries belonging to Asian region, the chart contradicts to what we established in the previous two plots. Here there is a very strong negative correlation between terrorism and happiness score, family and freedom, which is convincing because people are unhappy where terrorist attacks are more.
In the European region, no robust correlation can be inferred.Thus we can say that terrorist attacks in European region are not particularly influenced or related to any of the countries indicators.
Same as in the case of nations in the Asian region,we see similar type of correlation between terrorism and happiness score, family and freedom in the Middle east region.
In countries belonging to Northern/Southern American region, we can notice that, there is a negative correlation between terrorism and generosity.
